EPI Master Touch Series 8000MP Inline Flow Meter

Inline style thermal mass flowmeters include a flow section that is usually specified to match the user’s flow conduit and is then plumbed directly into the process line. This design has the sensing elements mounted directly in the flow section for exposure to the process gas.

The Master Touch flow meter includes a flow sensing element, temperature sensing element, analog bridge board, digital controller board and a transmitter enclosure. The flow sensor is mounted in an insertion probe support / averaging tube or an inline flow section. Depending upon your requirements, all of these components may be integrated into one flow transmitter assembly or you may have a flow transmitter and a second, remote electronics enclosure. In either configuration, the digital controller converts the nonlinear input signal received from the flow sensor to linear 0–5 VDC & 4–20 mA output signals. RS485 Modbus RTU communications are embedded in the firmware. HART and Profibus DPcompatible modules are optionally available.

**This item does not power on and is being sold AS/IS for parts. This flow meter will need to be validated/calibrated to ensure accurate results. See photos for details.
